SE2 SELF DIAGNOSTIC SOFTWARE
The identification of errors within the SE2 chassis is triggered in one of two ways :- 1: Busy or 2: Device failure to respond to IIC. In the event
of one of these situations arising the software will first try to release the bus if busy (Failure to do so will report with a continuous flashing
LED) and then communicate with each device in turn to establish if a device is faulty. If a device is found to be faulty the relevant device number
will be displayed through the LED (Series of flashes which must be counted).
